I bought the Soundpeats Q2 Mini for $9.99 at Amazon. They just got here and works great. Battery life is 6 hours. Not good for calls as microphone is junk but range is good I can now go to the bathroom or kitchen without wires.
I can shake my head and they stay put. I got two one for me and one for hubby.
If your looking for cheap Bluetooth that pairs with two devices give these a try. Audio is good and music is decent if you aren't super picky.
